Abstract
Abstract There is disclosed a silver halide color photographic material comprising a support having thereon a coupler-containing layer, wherein said coupler-containing layer is substantially free from high boiling solvent; and said coupler-containing layer or another layer contains a compound which upon reaction with an oxidation product of a developing agent releases a development inhibitor capable of changing to a less inhibitory compound, or a precursor thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
62 words
A silver halide color photographic material comprising a support having thereon a coupler-containing layer, wherein said coupler-containing layer is substantially free from high boiling solvent; and said coupler-containing layer or another layer contains a compound which upon reaction with an oxidation product of a developing agent releases a development inhibitor capable of changing to a less inhibitory compound, or a precursor thereof.
Claim 2
Dependent Claim
62 words
A silver halide color photographic material comprising a support having thereon a coupler-containing layer, wherein said coupler-containing layer is substantially free from high boiling solvent; and said coupler-containing layer or another layer contains a compound which upon reaction with an oxidation product of a developing agent releases a development inhibitor capable of changing to a less inhibitory compound, or a precursor thereof.
Claim 3
Dependent Claim
30 words
A photographic material of claim 1, wherein said coupler-containing layer contains a high boiling solvent of not more than 0.5% by weight of a total weight of coupler contained therein.
Claim 4
Dependent Claim
105 words
A photographic material of claim 1, wherein said compound is represented by the following formula: wherein Cp represents a coupler residue; T represents a bonding group whose bond with Z is broken after C P -T bond has been broken upon reaction with an oxidation product of a developing agent; Z represents a development inhibitor residue; L represents a bonding group having a chemical bond capable of being cleaved by a component contained in a developer; Y represents a substituent; m represents 0, 1 or 2; n represents 1 or 2; provided that when n is 2, L and Y may be identical or not.
Claim 5
Dependent Claim
90 words
A photographic material of claim 3, wherein said compound is represented by the following formulae (1) through (9) wherein Cp and -L-Y- have the same definitions as Cp and -L-Y- in Formula [DIR-I]; R 1 ' represents a substituent; R 2 ' and R 3 ' represent each a hydrogen atom or a substituent; ℓ' represents 0, 1 or 2; provided that when ℓ' is 2, the ℓ 1 ' groups may be identical or not, and may form a condensed ring; X' represents a hydrogen atom or a substituent.
Claim 6
Dependent Claim
32 words
A photographic material of claim 4, wherein said compound is contained in an amount of 1 x 10- 4 to 1 x 10 -1 mol% of a total amount of silver coated.
